Mysterious falcon decline: American Kestrel juveniles thrive amid population drop

North America's smallest falcon, the American Kestrel (Falco sparverius), has declined across the continent since the 1970s, yet the causes continue to stump raptor biologists. A new study published in the Journal of Raptor Research adds a piece to the puzzle with the discovery that in the Northeast, where declines are most alarming, fledglings demonstrate a relatively high survival rate.
